Computer-aided design (CAD) involves using computer technology to aid in the design process. CAD allows designers to visualize designs digitally in 3D and test variations without needing to produce physical prototypes. It has applications in fields like architecture, engineering, fashion design, and more. CAD originated in the 1960s and was initially used by large automotive and aerospace companies who could afford early computers. As computers became more affordable, CAD software spread to other industries. For fashion design, CAD enables viewing virtual models in different colors and shapes, saving time over iterative physical prototypes.
